A 10-month-old baby has contracted "acute" hepatitis in one of the youngest cases to date of a mysterious worldwide outbreak.
Singapore officials have confirmed the infant's diagnosis and are now investigating to see if the youngster presents similar symptoms to other children with the liver inflammation illness.
Lab tests found the baby was negative for the common viruses known to cause hepatitis - type A, B, C and E viruses - according to Singapore's Ministry of Health.
